[ https://issues.apache.org/jira/browse/MADLIB-1084?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Himanshu Pandey updated MADLIB-1084: Comment: was deleted (was: Hi [~fmcquillan] , In case of grouping in Personalized Page Rank, what if : # The nodes of interest are not present in the group? # Or only a subset of nodes of interest is present in the group. What will be the initial probability in this case? For eg: special nodes = 2, 3 Initial probability = 1 / number of special nodes = .5 for each special node Random Prob = 1 - .85 = .15 for each special node. {code} | |special nodes = 2, 3| | |Group 1|nodes|initial prob|random prob| | |1|0|0| | |2|0.5|0.15| | |3|0.5|0.15| | |4|0|0| | |5|0|0| | |6|0|0| | | | | | |Group 2| | | | | |3|0.5 or 1?|0.15| | |4|0|0| | |5|0|0| {code}) > Graph - Personalized PageRank > - > > Key: MADLIB-1084 > URL: https://issues.apache.org/jira/browse/MADLIB-1084 > Project: Apache MADlib > Issue Type: New Feature > Components: Module: Graph >Reporter: Frank McQuillan >Assignee: Himanshu Pandey >Priority: Major > Fix For: v1.14 > > > Personalized PageRank which is a variant of regular PageRank. > Please refer to > [http://madlib.apache.org/docs/latest/group__grp__pagerank.html] as a > starting point. > Reference: > Neighborhood Formation and Anomaly Detection in Bipartite Graphs > [http://www.cs.cmu.edu/~deepay/mywww/papers/icdm05.pdf] -- This message was sent by Atlassian JIRA (v7.6.3#76005)
